Who Needs

We champion Open Source development. As a result all our products:

Team working

Direct access to the software team, to discuss new features & working practices.

Training & support

Getting started support, including training & support for importing two in-house ASCII file types.

Fast bug fix request processing

Up to an agreed number days per month, typically delivered within two working days. It can take many days for an analyst to fully engage with the context of a trial/operation, to get into the mindset of the participants. Once broken this concentration can take many days to re-engage.

Responsive user support to analysts

To ensure they focus on delivering output. A knowledge worker “in the zone” is capable of delivering amazing insight. The lack of a support contract can mean that an analyst has to defer exploring a hypothesis – with the result that it may never be investigated.

Immediate access to Debrief updates

Including new features, delivered in enterprise-friendly form (.MSI installer). This reduces the workload on both analysts and the IT support infrastructure.

Stay in the zone

A quick turnaround feature request can let them “stay in the zone”.
